Analysis of clean heating renovation demand in rural areas of Shenyang

In recent years, with the in-depth promotion of clean heating pilot cities, significant progress has been made in the substitution of scattered coal in rural areas in northern China. In view of the clean heating renovation demand in rural areas of Shenyang, a survey on the current situation of rural heating is carried out, the actual heating effect is monitored, and the heating load is calculated and analysed by constructing a typical rural house model. By analysing the characteristics of outdoor temperature in the heating season in Shenyang, the frosting analysis of the air-source heat pump is carried out. This paper summarizes the clean heating demand in rural areas of Shenyang, and provides the accurate basis and technical guidance for the scientific renovation of rural clean heating. The clean heating equipment in rural areas of Shenyang should ensure that it can work normally at -25 ℃, the reference heating load of equipment selection is 132.85 W/m2, and the operating cost of each household in every heating season should not be higher than 2 000 yuan.
